vides a clock signal for the MRXD serial data stream. The MRXD
signal is changed on the falling edge of this clock. The signal is as-
serted when a RIC2A is receiving data from one of its network seg-
ments. Otherwise the signal is inactive.
vides an activity framing enable for the serial data stream. The sig-
nal is asserted when a RIC2A is receiving data from one of its
network segments. Otherwise the signal is an input.
vides a serial data stream in NRZ format. The data stream is made
up of the data packet and RIC2A status information. The signal is
asserted when a RIC2A is receiving data from one of its network
segments. Otherwise the signal is inactive.
tive high enable for an external bus transceiver (if required) for the
MRXC, MCRS and MRXD signals. When high the bus transceiver
should be transmitting on to the bus.
PACKET COMPRESS: This input is used to activate the RIC2A's
packet compress logic. A low level on this signal when MCRS is ac-
tive will cause that packet to be compressed. If PCOMP is tied low
all packets are compressed, if PCOMP is tied high packet compres-
sion is inhibited.
